Abstract[German]
Dichtungsanordnung (101, 201, 301) für ein Pitchrohr (103) eines Windkraftgetriebes. Die Dichtungsanordnung (101, 201, 301) weist mindestens einen Axial-Wellendichtring (111) und mindestens eine kreisringförmige, relativ zu dem Axial-Wellendichtring (111) verdrehbare Gegenlauffläche; wobei das Pitchrohr (103), der Axial-Wellendichtring (111) und die Gegenlauffläche koaxial zueinander ausgerichtet sind; und wobei mindestens eine Dichtlippe des Axial-Wellendichtrings (111) axial gegen die Gegenlauffläche verspannt ist.[English]
Proposed is a seal assembly (101, 201, 301) for a pitch tube (103) of a wind turbine gearbox. The seal assembly (101, 201, 301) has at least one axial shaft sealing ring (111) and at least one circular-ring-shaped counterpart running surface that is rotatable relative to the axial shaft sealing ring (111), wherein the pitch tube (103), the axial shaft sealing ring (111) and the counterpart running surface are oriented coaxially with respect to one another, and wherein at least one sealing lip of the axial shaft sealing ring (111) is braced axially against the counterpart running surface.[French]
L'invention concerne un ensemble joint d'étanchéité (101, 201, 301) pour un tube à pas (103) d'un multiplicateur de vitesse d'éolienne. L'ensemble joint d'étanchéité (101, 201, 301) présente au moins une bague d'étanchéité d'arbre axial (111) et au moins une surface de roulement homologue en forme d'anneau circulaire qui peut tourner par rapport à la bague d'étanchéité d'arbre axial (111) ; le tube à pas (103), la bague d'étanchéité d'arbre axial (111) et la surface de roulement homologue sont orientés coaxialement les uns par rapport aux autres ; et au moins une lèvre d'étanchéité de la bague d'étanchéité d'arbre axial (111) est serrée axialement contre la surface de roulement homologue.
